Changes in Armour?

Hi All,
I have been on Armour thyroid for about 6 years now, at varying dosages. I am currently on 45mg, but I seem to having symptoms again. My dr upped me to 60mg however I couldn't tolerate it at all so I went back to 45mg.
I have been sweaty, hot, cold, dry skin, achy, anxious, FATIGUED (OMG so fatigued) and of course the dreaded weight gain.
I was on a compounded thyroid med when Armour was off the market for awhile and I did ok on it. When armour came back, it seemed to have changed and really doesn't seem to be working as well....
Has anyone had the same problem? I've heard it should be chewed now but yuckkkkkk ....
I will make another appt with the dr to see if I can go back on the compounded formula and see if that helps. But I wanted to see if there are others having problems so I can relate them to my doc.

Armour no longer works at all for many former successful users, me included.
After it stopped working, I switched to Naturethroid. But it underwent a similar formula change and now, it no longer works for me.

After that, I went to compounded, which worked but was expensive. Then I went to Erfa thyroid I ordered from Canada. It worked fine.
Then, a new generic from Acella came on the market in the US. The name is NP Thyroid. I switched from Erfa to NP after I read numerous reports of its working like "old" Armour did. I also became nervous about the FDA perhaps retracting their permission to order it from Canada and didn't want to be left hanging without a suitable alternative.

I've been on NP for a year and find it is actually is working for me like old Armour did.

"New" Armour has a different (or increased amount of) filler - microcrystalline methylcellulose - than "old" Armour. The problem with that is, cellulose binds to levothyroxine. The human gut doesn't produce the enzyme needed to free the levo from the cellulose so it passes through undigested/unabsorbed. The drug that worked great in the "old" formula no longer works for many of its former users who suddenly found themselves hypo again after years-to-decades of euthryoidism. However, it does unexplainably still work for others. The only way to know is to try it.
However, if I were a newbie going into treatment with knowledge of Armour's history, I'd begin with NP or Erfa thyroid instead of merely hoping Armour would do the trick.
